SPECIFICATION forming part of Letters Patent No. 296,215, dated April 1, 1884.

Application filed January 7, 1884. (No model.)

citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented new and useful Improvements in Lubrioators', of which the following is a specification.

This invention relates to improvements in lubricators capable of being applied to ma-' chine and shaft journals, and has for its object to provide novel and efficient means whereby the oil-cup can be conveniently filled and the feed of the lubricant regulated without adjust ing or disturbing the cap or cover of the cup.

To such end the invention consists in a vertically sliding and rotating valve adapted to open and close the receiving-mouth of the oilcup, and provided with radial wings or flanges and a slotted extension or stem, the wings steadying and guiding the valve in its movements, and the extension or stem serving to engage and adjust a feed regulating device which controls the discharge of the lubricant from the cup.

The invention also consists of other features of construction and combination, all of which will be hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a vertical central sectional view of a lubricator embodying my invention; Fig. 2, a detached plan view of the valve which con trols the receiving-mouth of the cup and adjusts the feed-regulator; Fig. 3, a bottom plan view of the nut which confines the cap or cover of the cup in position, and Fig. 4 a sectional view on the line a: w of Fig. 3.

Referring to the drawings, the number 1 indicates the glass oil cup or reservoir; 2, the cap or cover; 3, the bottom of the cup, having the pendent screw-threaded shank 4, by which it is attached to the journal-box or other device to be lubricated. From the center of the bottom 3 rises vertically a tube, 5, having a discharge-orifice, 6, through it at the base for the feed of the oil from the cup, the upper end of the tube being screw-threaded, as at 7, which enters a screw-threaded neck, 8,which is j oincd bywebs 9 to a hollow cylindrical body, 10, such neck, webs, and body constituting a screw-nut, by means of which the cap 2 and bottom 3 are clamped upon the ends of the glass cup, suitable packing-rings, 11, being interposed between the cap and bottom and the cup to provide tight joints. The upper end of the screw 5 5 nut is threaded, as at12, to receive a screwring, 13, having an orifice, 14c, constituting the receiving-mouth of the cup, said ring being constructed with a valveseat, 15, around the edge of the said orifice. YVithin the cylindrical body 10 of the screw-nut is arranged a valve, 16, of such diameter as to close the orifice 14 when seated on the valve-seat 15, said valve having radial wings or flanges 1? on its under side, and apendent cylindrical extension or stem, 18, entering the upper end of the tube 5, and provided with a slot, 19, which loosely engages the upper square end, 20, of a rod, 21, located in the tube, and having a screw-thrcaded lower end entering the threaded discharge- 7o passage 22 of the attaching-shank 4. The lower end ofthe said rod is provided with a tapering or V-shaped groove, 23, and hence if the rod be turned to screw it downward, the feed of the oil is reduced by reason of the groove 23 passing further below the surface of the surrounding metal, and thus contracting the space for the discharge of the oil from the cup to passage 22. The slot in the stem of the valve 16 permits the latter to be moved vertically; but when the valve is rotated through the medium of a knob or handle, 24, the rod 21 is forced to turn, and therefore the rod is raised or lowered, according to the direction in which the valve is turned, and in the movements of the valve it 8 5 is accurately guided and steadied by the wings or flanges bearing against the interior of the cylindrical body of the screw-nut. In order to fill the oil-cup, the valve 16 is depressed away from its seat, and the oil is poured into the re- 0 ceiving-mouth, passing directly into the cup through the screw-nut. To adjust the feed-regulating device, and thereby control the quantity of oil discharged from the cup, the valve is rotated to the right or left until the desired adjustment is effected.

A small hole maybe drilled centrally through the valve and its knob to form a vent for the escape of air from the cup when the oil is poured therein, and a spring, 25, serves to automatically seat the valve in the receiving-mouth when downward pressure on the valve is removed.

It will be obvious that by the devices described the oil-cup can be filled and the feedregulating device adjusted at any time with out moving the cap or cover of the cup, and, further, that the sliding and rotating valve effectually closes the cup when upon the valveseat.

I have shown and described a peculiar construction of feed-regulator, but wish it understood that this device may be variously constructed and arranged.

Having thus described my invention, what I claim is 1. The combination, with an oil-cup having a feed-regulating device, of a sliding and rotating valve to the mouth of the cup, for supplying the cup with oil and adjusting the feed-regulau ing device, substantially as described.

2. The combination, with an oil-cup having an oil-receiving mouth, of a feed-regulating device and a sliding and rotating valve to the receiving-mouth, for supplying the oil-cup and controllingthe feed-regulating device, substantially as described.

3. The combination, with an oil-cup having a feed-regulating device and an oil-receiving mouth, of a sliding and rotating valve to the receiving-mouth, having a loose connection with the feed-regulator, whereby the valve can be slid to open the receiving-mouth without moving the regulator, and rotated to adjust the regulator,'substantially as described. v

4. The combination, with an oil cup having a feed-regulating device, of a vertically-movable and rotating valve having a slotted stem, substantially as described.

5. The combination, with an oil-cup having a feed-regulating device, of a vertically-movable and rotating valve having a slotted stem and radial guide wings or flanges, substantially as described.

. 6. The combination, with an oil-cup having a feed-regulator, and a ring provided with an oil-receiving orifice and a surrounding valveseat, of the vertically-movable and rotating valve for engaging the feed-regulator, and having means by which it can be depressed and rotated, substantially as described. I

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
